To all whom, it may concern:

Be it known that I, ERNST ZrLLnssuN, a subject of the Emperor ofGermany, residing at Crefeld, in the Kingdom of Prussia, Germany, haveinvented certain Improvements in Machines for Vashing and Dyeing Yarns,of which the following is a specification.

The object of myinvention is to construct a machine for the thorough andeliicient washing ot' yarns in the hank or skein, and also for wringing,squeezing, and pressing the hanks which have been washed and dyedwithout the removal of the hanks from the reels. This object I attain inthe man ner which Iwill now proceed to describe.

In the accompanying drawings, Figure 1 is a longitudinal side view,partly in section, of one form of my improved apparatus, in which thehanks may be treated on opposite sides of the machine. Fig. 2 is avertical section on the line A B, Fig. l. Fig. 3 is a plan view, alsopartly in section. Fig. 4 is an end view of the gearing for operatingthe tanks. Fig. 5 is a longitudinal section of one of myv singlemachines. Fig. 6 is-a transverse section of the same; and Fig. 7 is adetached view of the device for squeezing the hanks.

The hanks a of yarn are hung over a number of reels, b b,which areadapted to turn in bearings in the horizontal hollow reel-frame @,whichis carried by suitable standards. The longitudinal reel-frame c ishollow,and divided longitudinally by a central partition, and from thechambers'thus formed on each side project laterally in line with thereels b, and below the same, perforated tubes c, in such position thatthey will lie within the pendent hanks, as illustrated in Fig. l. W'ateris supplied to the two chambers in the hollow reel-frame through asuitable pipe, d', and the supply to each chamber is controlled by avalve, d, (Figs. l and 2,) so that water can be supplied to either orboth chambers, as may be found desirable. Rotary motion may be impartedto the reel by any suitable gearing, and as the hanks are therebyrotated the water introduced to the chambers in the hollow frame c willbe ejected through the perforatedpipes c onto the traveling hanks ofyarn to thoroughly wash the same. 1 By preference I use cold water forthe washing, and when it is de sired to subject the hanks to the actionof warm water, or ot' a dyeing or'mordanting solution, I makcuse of themovable tank or tanks f, which I will now describe. The tankf extendslongitudinally ofthe frame,and is adapted to be raised u p to the hanks,so that the lower parts of the latter, as they are turned by theirreels, are immersed in the liquid in the tanks, and washed, dyed, ormordanted thereby. Each tank f is supported at opposite ends by arms i,carried by a horizontal shaft, g, adapted to bearings in the posts 7L Itof the frame. Each tank isprovided at opposite ends with plates l,having pivot-pins k,adapted to bearings in the ends of the arms t'. Theshaft g carries a wheel, m', provided on a portion of its circumferencewith teeth, and ou the opposite side with a counter-weight, a, which maybe cast therewith, and mayalso be adapted to receive additionalweight-disks o where necessary. By means of this wheel it will be seen,as illustrated in Fig. 2, that the tank may be raised up to or movedaway from the suspended hanks, and for this purpose a hand-wheel, t, maybe provided to move the shaft g directly; but I prefer toprovideintermediate gearing, p t s, as may be found convenient. By meansof this gearing and the counter-weight the somewhat heavy tank may bemoved very easily from one side of the machine to the other.

The warm water or dyeing or mordanting solution may be introduced intothe tank through an india-rubber pipo, a, adapted to a nozzle in thebottom ofthe tank, andan overilow-pipe, o', is provided, through whichthe excess of liquid can escape into the collectingtrough below. Iprefer to so balance the tank that it will slightly outweigh theeounterbal ance a,so that it will firmly rest in its lower position topermit the washing ofthe hanks from .eitherside of the machine, and topermit the supply of water through the perforated pipes c. Vhen it isdesired to use the warm water or dye or mordant, the tank is raised, andit may be maintained in this raised Vposition by a suitable contrivance,such as pawl and ratchet or supporting-chains.

In the machine illustrated in Figs. 5 and 6 there is a tank, f, similarto that described, to be raised up to or lowered away from the suspendedhanks by means of the shaft and gearing before set forth; and I preferalso to supply a second tank, f', which is contained in the pit belowthe machine,and which is capable of being raised and lowered verticallyto or from the hanks when the tankf is moved out of the way. Themechanism for accomplishing this is shown in the drawings, and consistsof vertical racks m, carrying the tank f', and gearing into pinions y ona shaft, n2, Fig. 5, mounted in suitable bearings. This shaft n2 isprovided with pulleys, from which are suspended suitablecounter-weights, R, and also carries a chain-wheel, over which passes achain, z, gearing into a corresponding wheel, m2, on the shaft g, sothat the said shaft n2 may be turned from the shaft g, and through itspinions y can raise or lower thetank f. When the tank is in itsdepressed position, as illustrated in Fig. 6, while the rinsing or warmwater-washing processes are in progress, the said tank f', which isintended to contain the dye or mordant, is covered by a removable cover,d', hinged at its upper edge, so that as the said dye-tankf is raised itwill be thrown up to the posit-ion indicated by dotted lines inFig.6,where it lies against the side of the tank, and thus offers alateral protection to thelatter. As the tank f is intended to containthe dye or mordant in solution, the cover d', when the tank is -in thedepressed position, prevents the water or dirt from the washing processilowinginto the tank and diluting or adulterating the solution. Thedevices for raising and lowering the tank may,however,be constructed invarious ways without departing from my invention. In some cases I maycombine with the above-described mechanism devices for wringing,squeezing, or pressing the hanks which have been treated in tbemordanting and dyeing vats, and these devices are of more especial usewhere the dyeing, mordantin g, and washing processes are to be carriedout quickly one after the other, or where the mordant-vat has to befrequently replaced by a dyeiugvat. These wringing or squeezing devicesare illustrated in Figs. 5, 6, and 7, and consist of rollers g',suspended from suitable balanced arms over the rollers or reels b, sothat when the bath is finished the'banks are lifted up over the rollersg and are stretched by means of the counter-weights, and adjacent toeach of the rollers I) is a cylinder, q, which presses firmly againstthe roller or reel b and the bank thereon. Said cylinder q is carried byan arm of a bent lever on the shaft. The. arm h of this lever has a.bearing at its upper cnd,through which. passes the rod fi. A spring, m',between an adjustable regulating-collar, s', on the rod and the saidbearing,tends to press the cylinder q against the banks on the reels b.These reels b being rotated at this time all .parts of the travelinghank will be subjected to the squeezing operation. The disk z,which actsonthe longitudinal rodto regulate the pressure of the cylinder q,may beadjusted according to the pressure desired.

I claim as my invention- 1. A yarn washing, dyeing, or mordantingmachine provided with a movable tank, f, as and for the purpose setforth.

2. The combination of the frame and bankreels adapted to carry thehanks,with a longitudinal shaft having arms carrying a tank, whereby thelatter may be moved upv to or away from the said tanks.

3. The combination of a frame having hank reels on opposite sides, witha central longitudi nal shaft carrying arms, and a tank pivoted to saidarms, whereby the said tank may be moved up to the banks on either setof reels.

4. The combination of the frame carrying hank-reels, with a shaft havingarms, a tank pivoted to said arms, and a counter-weight on the shaft.

5. The combination of the frame having i hank-reels, and a shaft havingarms, with a tank pivoted to the said arms, a counterweighted wheel onthe said shaft, gearing, and hand-wheel t. q

6. The combination of a frame carrying bank-reels, and a shaft havingarms carrying apivoted tank, f, with avertically-movingtank, f', belowthe bank-reels, subst-antially as described. I

7. 'Ihe combination ofthe frame carrying bank-reels and dyeing orwashing tanks, with rollers g over the reels, and counterbalanced armsfrom which the said rollers are suspended, substantially as described.

8. The combination of the frame carrying hanklreels, with avertically-moving tank, f', below the said reels, and a pivoted cover,d', for the tank, substantially as and for the purpose set forth.

In testimony whereof I have signed my name to this specification inthepresence of two subscribing witnesses.
